1) You can do this by leading with the thumb. That would be twisting by wrist.

2) You can do this by turning around the elbow. That would be twisting by forearm.

I think it might be easier if you properly visualize the non-hitting arm as we discussed before. The hitting arm will usually follow in kind after that. You were really, really close that time, but the mismatch of the non-hitting arm and the hitting arm threw off your timing.

Yea, but non-hitting arm aside, what is the proper method to initiate the racket turn? a twist of the forearm? a twist of the wrist? or something else?
